Some weeks ago, a forum member, jinkgraph I think, mentioned talking with a person who was having a .405 double rifle made by a gunsmith in north Louisiana. A recent post on Leverguns.com may have identified that gunsmith as Clark Custom guns - it seems they are making doubles in several popular calibers. Here is link to a video that demos the .405 WCF version. Please note that they are getting 2150 fps with 400 grain bullets - enjoy:

Here is a link to their web site:
